Struct RandomId 

pub(crate) struct RandomId(u128);

128 random bits from the operating system, written as 32 lowercase hex digits.

Tuple Fields

0: u128

Implementations

impl RandomId

const LEN: usize = 32

The length of the written ID.

pub(crate) fn new() -> Self

A new random ID. Panics if the operating system has no randomness, which Linux always has.

Trait Implementations

impl Clone for RandomId

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for RandomId

impl Debug for RandomId

The first 8 hex digits of fmt::Display, which tell the IDs in a log apart without handing them out: the token of a request which got rejected stays valid.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for RandomId

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for RandomId

impl FromStr for RandomId

Only exactly 32 lowercase hex digits, the way they get written, without a sign or other characters.

type Err = InvalidRandomId

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for RandomId

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for RandomId

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
